Economical clear acrylic is ideal for general purpose processing. Amber is a ideal for UV protection, Transparent Static-Dissipative PVC eliminates static charges keeping the dry box clean and it does not attract particles from the air. Clear Non-dissipative PVC is a good choice for operations with many corrosive chemicals.

While inside humidity level is below set point the system provides low purge (2-20 Cubic feet per hour). Maintain positive pressure inside the desiccator chambers to have free contaminants and moisture environment.

When the moisture climbs above an adjustable set point the system automatically activates high-flow purge (0.5 - 60 PSI).

>> In One-channel purge control unit, there is only one humidity sensor which is installed in the lower chamber of multi-chamber desiccators. There are some perforated holes between chambers which connect the chambers together.

>> For more critical requirements, select the Multi-Channel nitrogen purge control unit. For each chamber there is separated sensor and controller. When any door opens the system responses much faster to the sudden RH% increase.
